Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic styluses are limited by their internal space and shape structure, restricting the size and performance of electrodes, which affects writing performance.
Innovation Solution
The electronic stylus integrates multiple electrodes into the pen core, which are detachably connected to the pen body, allowing for increased electrode size and layout space without affecting appearance, and includes a threaded connection for efficient assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If electrodes are provided inside the pen body, then the pen structure is compact, but the electrode size is limited and writing performance is restricted
Solution Approach 1:
The patent moves electrodes from the internal space of the pen body to the front-end pen core, utilizing the tip area of the stylus. This dimensional relocation allows electrodes to be positioned in a previously underutilized space, enabling larger electrode areas without increasing pen body volume.
Solution Approach 2:
The patent divides the stylus into separable components: a pen body and a detachable pen core. The pen core contains the electrodes and can be independently replaced. This segmentation allows the electrodes to be positioned at the front end while maintaining a compact pen body design.
2Device complexity
If only one electrode is provided in the pen core, then the pen core structure is simple, but the writing performance and performance adjustability are limited
Solution Approach 1:
The patent integrates multiple electrodes (first electrode, second electrode, and third electrode) into the pen core structure. These electrodes are arranged in specific spatial relationships and work together to provide enhanced writing performance, tilt angle detection, and position information, transforming a simple single-electrode design into a multi-functional system.
3Area of moving object
If multiple electrodes are integrated in the pen core, then electrode size and layout space are increased, but the pen core assembly becomes more complex
Solution Approach 1:
The patent separates the pen into a pen body and a detachable pen core, with the pen core containing all electrodes. This segmentation allows complex electrode integration to be isolated in the pen core module, which can be pre-assembled and tested independently before attachment to the pen body, simplifying the overall manufacturing and assembly process.
Solution Approach 2:
The pen core is designed as a universal module that can be detached and replaced. It integrates multiple electrodes (first electrode for position, second electrode for tilt angle, third electrode for additional functions) that work together to provide multiple functions within a single replaceable component.
